Mother Dairy, the largest supplier of milk in the Delhi-NCR, sells more than 30 lakh litres per day (both loose and poly-pack) in the region.

"Price hike has been necessitated due to significant increase in raw material costs (farmer prices) by almost 10 per cent over last year, power tariffs, petroleum prices and other costs," the company said.

Prices have been increased to maintain viability of operations and to be able to adequately cater to the growing liquid milk demand of the consumers in NCR, it added.

Early this month, Amul had increased milk prices by Rs 2 per litre.

The company in statement said it "passes on 75-76 per cent of the consumer price to rural farmers. This may probably be one of the best and most efficient means of ensuring inclusive growth".
